- W2564822067 abstract "Advances in crystal growth allow for precise control of crystal phase in semiconductor nanowires. The arising novel materials, like wurtzite gallium arsenide (wz-GaAs), are promising options for new and improved, mainly optoelectronic devices. To do this, however, intensive investigation into their electroninc band structure is needed. This can for example be achieved by optical spectroscopy like photoluminescence spectroscopy (PL), photoluminescences excitation spectroscopy (PLE) or resonance Ramam scattering (RRS).To date, many different values for the fundamental bandgap and higher electron and hole state energies have been reported and the band structure of wz-GaAs is still controversially discussed. In order to support the results gathered with an established PLE setup, it is desirable to conduct RRS measurements as well.This work reports about the implementation of RRS into an existing PLE setup. Tests on wz-GaAs nanowires revealed a bandgap energy of 1.525 eV at low temperature (4 K) and of 1.46 eV at room temperature (295 K). Polarization dependent measurements suggest a Γ_{9v} → Γ_{7c} transition between the heavy hole band and the lowest conduction band. For transitions from the light hole band to the first conduction band a temperature dependence following the empirical Varshni equation has been found, yielding a light-hole heavy-hole splitting of about 50 meV at low temperature that rises to 90 meV at room temperature." @default.
